India passes 20 million cases amid oxygen shortage

India has recorded more than 20 million Covid infections, but the government says that cases are "slowing down". 

The country added more than 355,000 cases on Tuesday, down from more than 400,000 daily cases on 30 April. 

But testing numbers have dipped as well, sparking fears that India's true caseload is far higher. 

Case numbers, however, have been consistently falling in Maharashtra state, which had driven the second wave since early April.
